Correct Answer: A reference variable provides an alias to a previously defined variable Data -type & reference-name = variable name

Correct Answer: A destructor is automatically called when the object is destroyed A virtual destructor in C++ is used primarily to prevent resource leaks by performing a clean-up of the object

Correct Answer: All the features of C are similiar to C++ except some features, such as polymorphism, operator overloading which are supported in C++ but not in C language Both C and C++ language is similiar in their functionality but C++ provides with more tools and options

Correct Answer: It is necessary to understand some of the concepts used extensively in object oriented programmingThese include Objects Classes Data abstraction and encapsulation Inheritance Polymorphism Dynamic Binding Message passing

Correct Answer: C++ is created by Bjarne Stroustrup of AT&T Bell Labs as an extension of C, C++ is an object-oriented computer language used in the development of enterprise and commercial applications Microsoft?s Visual C++ became the premier language of choice among developers and programmers

Correct Answer: Copy constructor is a constructor function with the same name as the class and used to make deep copy of objects

Correct Answer: A default constructor is a constructor that either has no parameters, or if it has parameters, all the parameters have default values

Correct Answer: Dynamic binding (also known as late binding) means that the code associated with a given procedure call is not known until the time of the call at run timeIt is associated with polymorphism and inheritance

Correct Answer: The C++ language provides a single global namespaceNamespaces allow to group entities like classes, objects and functions under a name

Correct Answer: Late binding refers to function calls that are not resolved until run time Virtual functions are used to achieve late binding When access is via a base pointer or reference, the virtual function actually called is determined by the type of object pointed to by the pointer
